Wireless Modules
4G LTE Modules
LTE Cat.1 and Cat.4 modules for devices that need wide-area coverage without depending on a local network.
Overview
When a device is installed in the field — a pumping station, a cold room, a vehicle, a remote meter — there is no Wi-Fi to rely on. A 4G LTE module gives that device a wide-area uplink that works across a mobile network, with the SIM and data plan managed by you or your customer.
LTE Cat.1 has become the practical default for telemetry: it delivers enough throughput for periodic sensor uploads, firmware updates and occasional images, while consuming and costing considerably less than Cat.4. Cat.4 remains the right choice when the product has to stream video or move larger files.
We supply modules with AT command interfaces, GNSS variants, and optional integrated SIM or eSIM holders. On the firmware side we handle the parts that cause most field failures: PDP context activation, automatic reconnection, buffered uploads after coverage loss and power management for battery-backed designs.
Capabilities
What this covers
Cat.1 and Cat.4 options
Category 1 for cost-sensitive telemetry, Category 4 for higher-throughput applications such as video or bulk transfer.
Standard AT command set
Familiar AT interface for quick integration with an existing host MCU, plus a documented command reference.
Resilient data link
Automatic PDP re-activation, reconnect backoff, offline buffering and retransmission after coverage loss.
GNSS variants
Combined LTE + GPS/GNSS module options for tracking products that need both uplink and position.

Questions
Frequently asked
Which LTE bands do you support?
Band support depends on the module variant. We match the variant to your destination markets and confirm carrier compatibility before shipping.
Can the device keep data during a network outage?
Yes. We implement local buffering with retransmission, so readings collected during an outage are uploaded once coverage returns.
Do you provide the SIM card and data plan?
We can supply industrial SIMs through partners in some regions, but most customers use their own carrier or an IoT connectivity provider.
